Introduction

We're going to be using spawn/save points and Dreamgates to our advantage in favour of giving the flower to everyone you can see. Well, everyone you can, at least. While not as practical for early game play, it certainly is helpful for whoever wants to see all the content (mostly lore) they can using the Delicate Flower.

Finding the Grey Mourner

Now that that's out of the way, take the Stag to the Resting Grounds. If you haven't already destroyed it, you may notice there is a breakable tomb below the Stag Station when you drop to the bottom. Use Desolate Dive/Descending Dark on it, which will drop you into an underground cave. Go right and break the wall revealing a longer corridor. Go down, and at the end, look for a breakable ceiling. Break it and enter the room above. Entering the building to your right, you will find the Grey Mourner.

Traitor Lord's Daughter

Caution! This is the only flower route that I haven't tested!

The Grey Mourner will ask of you to bring the Delicate Flower to the grave of the Traitor Lord's daughter in Queen's Gardens. First, you will place a Dreamgate at the outside of the Grey Mourner's building. Next, exit the cave and use the Stag to ride to Queen's Gardens, despite the flower being destroyed upon riding.

Important!

Save at the nearby bench in the Stag Station, and then use your Dreamgate to go back to the Grey Mourner; once there, request another flower. After recieving the flower, go to the pause screen and quit to the menu. Load up your save again and you'll be sitting on the bench in the Stag Station at Queen's Gardens. Then simply exit to the right, climb the room, and then enter the room with the grave of the daughter. Placing your Flower at the grave will cause many other flowers to grow around the grave, and have a mask shard waiting for you back at the Grey Mourner.

Elderbug

Set a Dreamgate at the grave of the Traitor Lord's daughter, had you not already done so. Exit the room with the grave, drop to the bottom of the room and enter the Stag Station. Take the Stag to Dirtmouth, and sit down on the bench. Afterwards, use the Dreamgate back to the grave. Pick one of the flowers, and enter the pause screen, and quit to the menu. Enter your save file, and you'll be back at the bench in Dirtmouth with the Delicate Flower, and give the Flower to Elderbug.
Adorable.

Nailmaster Oro (Godmaster)

Set a Dreamgate at the grave of the Traitor Lord's daughter, had you not already done so. Exit the room with the grave, drop to the bottom of the room and enter the Stag Station. Take the Stag to King's Station, leave to the left and fall to the bottom, and enter the room at the bottom right. Enter through the hole in the wall and enter Kingdom's Edge through the Tower of Love. Follow the route to Nailmaster Oro. Sit on the bench outside of his home. Afterwards, use the Dreamgate back to the grave. Pick one of the flowers, and enter the pause screen, and quit to the menu. Enter your save file, and you'll be back at the bench outside of Nailmaster Oro's house with the Delicate Flower, and give the Flower to Nailmaster Oro. He'll first deny it, but enter the room again and you'll see the flower in a nice pot.

The Godtaker (Godmaster)

Important!

If you haven't unlocked the Godtaker, bring a simple key with you!

Set a Dreamgate at the grave of the Traitor Lord's daughter, had you not already done so. Exit the room with the grave, drop to the bottom of the room and enter the Stag Station. Take the Stag to King's Station, and navigate to the Waterways.

Once you've made your way to the Junk Yard, if you haven't already, unlock the Godtaker and enter his dreams. After you have exited, use the Dreamgate back to the grave. Pick one of the flowers, and enter the pause screen, and quit to the menu. Enter your save file, and you'll be back at the Junk Yard with the Delicate Flower, so give the Flower to the Godtaker. This unlocks a new ending after beating the 5th pantheon.
